EDMUND SIDNEY CLARK, OF ADELAIDE, SOUTH AUSTRALIA.

HANDLE-BAR FOR/.BICYCLES.

SPECIFICATION forming part of Letters Patent No. 614,088, dated November 15, 1 898.

Application filed October 2, 1897. Serial No. 653,834. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDMUND SIDNEY CLARK, a subject of the Queen of Great Britain, residing in Adelaide, South Australia, have invented certain new and useful Improvements in Handle-Bars for Bicycles andthe Like, of which the following is a specification.

My invention relates to certain improvements in and connected with handle-bars of bicycles and the like, the special object of the invention being to provide means whereby the vibration of the handle-bar may be reduced when traveling over rough and uneven tracks.

In order to achieve the object of my invention, I construct and fit my handle-bar in such a manner as to allow it to partially revolve within a suitable socket, an adjustable springear and intermediate attachments being provided to assist in maintaining the handle-bar in a convenient position.

I will now proceed to describe my invention in detail, having reference to the accompany ing illustrative drawings, in which similar letters of reference are used to denote similar or equivalent parts wherever they occur.

Figure 1 is a side view of the appliance in section. Fig. 2 is a plan of same with the upper portion of socket or cover removed, the under side of cover being shown inFig. 2 Fig. 3, back elevation of the appliance; Figs. 4 and 5, sectional side view and back elevation, showing further details of construction on larger scale.

A is a handle-bar of any convenient shape, to which a segment plate or lug B is attached. The segment-plate is slotted at B.

O is the socket for supporting the handlebar, the upper part or cover 0 of the socket being detachable. The cover 0 may be held in place either by bolts and studs B at front and back, as in Figs. at and 5, or it may be hinged in front at B, as indicated in Figs. 1, 2, and 2. Within the cover a recess B as indicated in Fig. 2 is formed, the recess being of such size as will enable the segment plate or lug B, above mentioned, to freely,

turn therein.

D is the handle-bar stem, to which the base of the socket is securely brazed or otherwise attached, a small hole or passage E being formed through the socket 0 immediately above the vertical center line of the stem.

F is a pin or rivet which passes through the slotted portion of the segment-plate B and secures one end of a flexible wire or chain G Within the slot B. The opposite end of the wire or chain G is passed through the passage E and is attached to the upper end of a coil-spring H. To the lower end of the coilspring an adjustable screw J is attached. The free end of the screw passes through a plug K, a tension-nut L being provided for purposes of adjustment.

With a handle-bar arranged in the manner indicated I prefer to use an ordinary pressbrake, the head of which is indicated at M in Fig. 1, as will be well understood on reference to the drawings.

If so desired, my handle-bar may be held rigid while the rider is mounting the machine. In order to achieve this object, I constructa pivotally-mounted trigger N, as illustrated in Figs. 4: and 5 of the drawings. This trigger is provided with a thumb-press N, whereby the beveled end N of the trigger N may be thrown in or out of gear with the back of the lug or segment-plate B of the handle-bar at the will of the operator. The trigger is con trolled by a spring N arranged in any wellknown way.

It will readily be seen that by the peculiar construction and arrangement of the several parts hereinbefore described the elasticity of the spring will afiord an ample means for minimizing the vibration of the handle-bar.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In improvements in and connected with handle-bars of bicycles and the like, a revolubly-mounted handle-bar having a lug B there- I on, a flexible wire or bell chain G, a tension spring H, and an adjustable screw and nut J and L, all substantially as described and illustrated, as and for the purposes set forth.

2. In combination, the socket, the handlebar revolubly mounted therein having a lug,

a tension-spring connected with said lug on one side, and a spring-pressed trigger adapted to contact with said lug on the opposite side to hold it against movement, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDMUND SIDNEY CLARK.
